Goody bags are becoming a regular feature at functions and trade-shows. Even at the MATTA (travel) fair, each visitor to the fair is given a goody bag. One has to pay to gain access, of course, but I was there several years ago but they did not do that then.
Anyway, what do you normally find in a goody bag? I've found regular items such as brochures, vouchers and coupons, discount and name cards, promotional pens, sample vials of perfumes, miniature lipsticks, pins and brooches, t-shirts, books and magazines, scarves, scented candles, teddy bears, even a mug. Well, what I really wanted is a key to a house or a posh car. lol No such luck.
